ing that one-half of the fiirfurol yielding substances are available 
as food for the ruminant. This is probably not far from the facts 
in the case, but it will be seen from the following table that we have 
very good reasons for doubting whether the complexes are equally 
attacked as we assume in making this statement.

§73. The results in this table are unsatisfactory, but we re¬ 
peated a number of the determinations and found no error. The 
discrepancy between the coefficient found by summing up the 
amounts in the individual extracts of the hay, orts and dung and 
that found by determining the furfurol in the hay, orts and dung 
themselves is altogether too great, but the amount digested in either 
case is comparatively small and large differences result from com¬ 
paratively small errors in the work. The general coefficient found 
was 50.12. 
COEFFICIENT OF DIGESTION OF THE METHOXYE GROUP IN 
TIMOTHY HAY. 
§74. The orts, as in the case of the alfalfa, have been consid¬ 
ered as containing the same percentage of methoxyl as the hay, 
which is probably not correct, but this error can be neglected as the 
difficulties of the determination do not permit of great accuracy at 
the best. The hay consumed contained 124.20 grams; there was 
voided 103.70 grams; digested 20.5 grams, or 16.50 per cent. 
digestibieity of the amids in timothy hay. 
§75. The amid nitrogen found in the timothy hay used, cor¬ 
responded to 0.99 per cent, of proteids, or 0.168 per cent, nitrogen 
and that found for the orts was almost identical, 0.994 per cent.; in 
the feces we found none. According to this the amid nitrogen is 
wholly digestible. 
§76. This result is aparently not in accord with the results 
given under the next caption, but we found no amid nitrogen in the
